Configuring Temporary Tables for Batch and Online Processing
When you run Application Engine processes in parallel, you risk data contention and deadlocks on temporary tables. To avoid this, PeopleTools enables you to dedicate specific instances of temporary tables for each process. When a PeopleSoft Application Engine manages a dedicated temporary table instance, it controls the locking of the table before use and the unlocking of the table after use.
When you decide how many temporary table instances to dedicate for a process, consider the number of temporary tables that the process uses. More instances result in more copies of the temporary tables on the system. For example, if a process uses 25 temporary tables and you have 10 instances for a process, you will have 250 temporary tables on the system.
If you run processes in parallel and all of the dedicated temporary table instances are in use, the performance of the process decreases. You must find a balance that works for your organization.
Note: When you specify the number of instances, PeopleSoft Application Designer displays a list of the temporary tables for the process. Use the list to determine how many temporary tables that each process uses.

The PeopleTools documentation discusses the use of temporary tables in detail and discusses how to specify the number of instances. See the product documentation for PeopleTools: Application Engine
If you run any of the PeopleSoft General Ledger COBOL processes, configure the temporary tables for those processes as well.
